What are the three defenses of long-acting thermal sensitive paper, and how to measure its protective effect?

Long-acting thermal paper refers to thermal paper with water, oil, alcohol (sometimes also interpreted as scratch or PVC) characteristics. This kind of thermal paper on the basis of ordinary three heat sensitive paper, through improving the production process and coating technology, further improve its durability and protection effect.

Three defense characteristics

1.Water proof: The long-lasting heat-resistant paper can effectively resist the erosion of moisture, and can keep the printed information clear and readable even in wet environments.

2.Oil proof: Strong resistance to oily substances, suitable for occasions that need to contact oil stains, such as catering, supermarkets, etc.

3.Alcohol proof: Alcohol is a common solvent, and the long-acting heat-proof paper can prevent alcohol from dissolving and destroying the printed information, ensuring the long-term preservation of information.

Measure of protective effect

The protective effect of long-acting three heat-proof paper is mainly measured by the following aspects:

1.Laboratory test: By simulating the actual use scenario, the thermal paper is tested for water resistance, oil resistance and alcohol resistance. For example, thermal paper samples are soaked in a specific concentration of water, oil or alcohol for a certain period of time to observe the retention of printed information. At the same time, wear resistance, scratch resistance and other tests can also be carried out to evaluate the durability of thermal paper.

2.Standard comparison: Refer to national or industry standards, such as "QB/T 2694-2005 thermal paper", etc., to evaluate the protective performance of thermal paper. These standards usually specify test methods and evaluation indicators, such as image retention, used to quantify the protective effect of thermal paper.

3.Practical application feedback: Through the user's feedback in the actual use process, to understand the protective effect of long-acting three-proof thermal sensitive paper. User feedback can reflect the performance of thermal paper in different environments, including its durability, clarity, stability and other aspects.

Influencing factor

The protective effect of long-acting thermosensitive paper is affected by many factors, including paper quality, production process, coating formulation and storage environment. Therefore, when choosing long-acting three thermal sensitive paper, it is necessary to consider these factors comprehensively and choose according to actual needs.

To sum up, the protective effect of long-acting thermal paper is measured by laboratory testing, standard comparison and practical application feedback. When choosing, the user should choose according to the actual needs and environmental conditions to ensure that the thermal paper can meet the requirements of use.
